I would expect that this is more or less Bookworm related - the GPIO access is different now - and need to be adapted

Hello. Is there an Example for BACnet IP Client in Codesys? An applicable example makes it pretty easy to understand.

why not simply converting data type UINT to INT? Then avoid negative values with ... := MAX(0 , intTest); Good luck!

Post by tk096 on Max lines of code, codesys CNC ? ^{CODESYS Forge talk (Post)}
Hi, this is a bug in CODESYS Softmotion. Due to this bug the size is limited to a maximum of 32767 elements. However, we recommend to use way smaller buffer sizes. You could use a small buffer (it should be big enough so that it does not run empty when the interpolator processes the elements). In the beginning you fill the buffer in PLC_PRG until it is full. Afterwards, you start the interpolator. The interpolator processes the elements and removes them as soon as it travels past them. In PLC_PRG you check whether new elements can be stored in the buffer (NOT QUEUE.bFull). If the buffer has space, you generate the next elements and add them to the buffer (SMC_AppendObj()). I hope this helps you.

Were you able to fix this? I had a program with motion working (several actually) and now bus not running. I'm stuck!

Post by s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
Hi, I want to use two OneWireMaster on a Raspberry Pi5. I'm running Codesys Control for Raspberry Pi 64SL V 4.15.0.0. Under Linux I've configured two GPIOs for 1w bus usage on GPIO4 and GPIO27. Under Linux both masters seem to work fine and I can readout both sensors connected to both GPIOs. The two masters are 'w1_bus_master1' and 'w1_bus_master2'. In Codesys I've configured to OneWireMasters with the corresponding file paths. But in Codesys the 2nd onewiremaster "w1_bus_master2" doesn't work. Status is showing "OnewireMaster : Not running" What am I doing wrong? Does Codesys on Raspberry support multiple OneWireMasters? Any help is appreciated.

Post by buczekj on About CPU Loading ^{CODESYS Forge talk (Post)}
This is a phenomenon that I have seen myself and with others. Texas instruments wrote an application note with this same issue. They noted with Codesys 3.5.19.10, that selecting CPU 1 as the EtherCAT task showed CPU spiking improvements over the performance of cores 0, 2, and 3. It appears to be linked to EtherCAT, are you configuring for use with distributed clocks? If so, I recommend choosing the 'Based on Input Reference' option. I have found it to reduce the CPU usage spike maximum slightly (see attached). See link to TI (also attached in case link breaks) https://www.ti.com/lit/an/spradh0/spradh0.pdf?ts=1723546111357

Post by timvh on Dynamically enabling/disabling Modbus slave devices in runtime (performance issue with timeouts) ^{CODESYS Forge talk (Post)}
As far as I remember, the Reconfigure functionality doesn't work for Modbus devices. But... Each Modbus device in your device tree has a name. You can set the property "Enable" of this device to FALSE to stop communicating with it. So if one of your Modbus Slave devices name is "MbSlave1" in the device tree, then in your code you can set the Enable to FALSE to let it stop communicating: MbSlave1.Enable := FALSE; Please let us know if this worked on your controller with your application and your CODESYS version. Alternatively you could use the ModbusFB library. See: https://forge.codesys.com/prj/codesys-example/modbus/home/Home/
